  1. 1. Power system balancing in Swedish future scenarios of 2045 - Estimating contributions from V2G

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Pontus Herrmann; Julia Jonasson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The ongoing climate change calls for an immediate decarbonization of society, where one important measure is a rapid transition of the energy system through an expansion of variable renewable energy sources, such as wind and solar photovoltaic power production. This transition imposes new challenges to the electrical power system, not least from a power balance perspective. LÄS MER

    Sammanfattning : Title: Improving charging scheduling of public transport electric buses Authors: Anna Hassler & Franz Bamberg Supervisor: Johan Marklund, Lund University Background: This thesis focuses on a Swedish BTO that operates EB fleets. For companies investing in electrification, record-high and volatile electricity prices, present challenges and creates a need to improve the charging scheduling of EBs to reduce costs. LÄS MER

  4. 3. Battery Storage as Grid Reinforcement for Peak Power Demands

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Jesper Hilleberg; [2023]
    Nyckelord :Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

    Sammanfattning : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

  5. 4. Potential and challenges of Battery Energy Storage(BESS) : The case of Poland

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Marcin Ziółkowski; [2023]
    Nyckelord :BESS; energy storage; electricity markets; ancillary services; techno-economic analysis; energy policy; EU direetives;

    Sammanfattning : According to the “Draft development plan for meeting the current and future electricity demandfor 2023-2032” developed by the Polish Transmission System Operator PSE, the most appropriate solution is to significantly expand the possibilities of energy storage, due to its role as a factor improving the power balancing with the increase of wind farms and photovoltaic (PV) sources. Poland has changed the rules governing the energy industry to encourage energy storage. LÄS MER

  7. 5. Tekniska lösningar för att hantera laddning av elbussar vid effektbrist : En analys av Uppsalas stadsbussdepå i olika framtidsscenarion

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Ebba Björk; [2022]
